Yesterday, Katy broke the news on Twitter that she is releasing her third fragrance, called Killer Queen, and even shared a picture of the regal gold and ruby bottle. (Details about the scent itself are being kept secret, but we do know it will be released this fall.)

Later in the night, Katy celebrated her new beauty venture at a launch party. And naturally, she dressed for the occasion wearing a super-dramatic red-and-white rose-printed Thom Browne ballgown to play off of the perfume bottle and royal name.

Considering how head-turning her dress was, she kept the rest of her look relatively simple -- except for her nails. Katy tweeted a close-up of her manicure and we were floored when we saw it! She rocked a ruby red base with opulent gold detail -- it's one of the craziest (a.k.a. awesome) manis we've seen in awhile.

So though Katy may be going for more classic looks as of late, she certainly still knows how to have some (stylish) fun.

Tell us: What do you think of Katy's dress and manicure? Are you excited to try Killer Queen?
